Abstract

A charging cable identification system is provided for a vehicle driven at least partially electrically, wherein the vehicle has an energy store that can be connected to an electrical energy source by a charging cable. The charging cable system has a control unit that is configured to enable or prevent the starting of the vehicle motor. The control unit is also configured to detect, prior to every event that is or can be predetermined, whether the charging cable is in the vehicle, and if the control unit detects that the charging cable is not in the vehicle, the control unit prevents the vehicle motor from starting.

First claim

What is claimed is:

1. A charging cable recognition system for an at least partly electrically operated vehicle, wherein the vehicle comprises an energy store that is able to be connected to an electrical energy source by way of a charging cable, comprising:
a control unit that is configured to allow or prevent starting of an engine of the vehicle, wherein the control unit is additionally configured to:
upon each predetermined or predeterminable event, to detect whether the charging cable is situated in the vehicle;
upon detecting that the charging cable is not situated in the vehicle, prevent starting of the engine of the vehicle;
determine, based on a state of charge of the energy store, that journey is able to be completed without using the charging cable; and
suppress an output from being received based on the determination, wherein
the output indicates the charging cable is not situated in the vehicle.

2. The charging cable recognition system as claimed in claim 1 , wherein
if the control unit detects that the charging cable is not situated in the vehicle, a corresponding message is output to a user of the vehicle via an output unit.

3. The charging cable recognition system as claimed in claim 1 , further comprising:
a charging cable receiver or charging cable holder for receiving the charging cable; and
at least one sensing unit that is able to sense whether the charging cable is situated in or on the charging cable holder,
wherein the control unit is able to be electrically connected to the at least one sensing unit and is able to detect, with the aid of the at least one sensing unit, whether the charging cable is situated in the vehicle.

4. The charging cable recognition system as claimed in claim 3 , wherein
the sensing unit is a weight sensor that is able to sense a weight exerted on the charging cable holder by the charging cable, and
the control unit is able to use the weight exerted on the charging cable holder by the charging cable to detect whether the charging cable is situated in the vehicle.

5. The charging cable recognition system as claimed in claim 3 , wherein
the at least one sensing unit may comprise one or more of:
a weight sensor that is able to sense a weight exerted on the charging cable holder by the charging cable;
a light barrier that is able to sense whether the charging cable is situated in the charging cable holder, and
a socket in the vehicle to which the charging cable is able to be connected on the vehicle side in order to charge the energy store and that is able to recognize whether the charging cable is connected to the socket; wherein the control unit is able to detect, with the aid of the one or more sensing units, whether the charging cable is situated in the vehicle.

6. The charging cable recognition system as claimed in claim 1 , further comprising:
at least one reader that is capable of reading RFID and/or NFC tags,
wherein the charging cable comprises an RFID and/or NFC tag with a unique identifier.

7. The charging cable recognition system as claimed in claim 6 , wherein
the control unit is able to use the reader to detect whether the charging cable is situated in the vehicle, and/or
the control unit is additionally able to use the reader to detect where the charging cable is situated in the vehicle.

8. The charging cable recognition system as claimed in claim 7 , wherein
the RFID and/or NFC tag may be used:
to perform an authentication in order to activate the electrical energy source; and/or
to pay for a procedure of charging the energy store using the electrical energy source.

9. The charging cable recognition system as claimed in claim 6 , wherein
the RFID and/or NFC tag may be used:
to perform an authentication in order to activate the electrical energy source; and/or
to pay for a procedure of charging the energy store using the electrical energy source.

10. An at least partly electrically operated vehicle comprising a charging cable recognition system as claimed in claim 1 .

11. The charging cable recognition system as claimed in claim 1 , wherein
the journey is a planned or past journey; and
the determination is based on one or more of:
a state of charge of the energy store; and
a current position of the vehicle.

12. The charging cable recognition system as claimed in claim 1 , wherein
the control unit is additionally configured to:
allow, based on the determination that the journey is able to be completed without using the charging cable, starting of the engine of the vehicle.

13. The charging cable recognition system as claimed in claim 12 , wherein
the journey is to a last position of the vehicle at which the charging cable was detected.

14. The charging cable recognition system as claimed in claim 12 , wherein
the journey is to a last position of the electrical energy source at which the charging cable was detected.

15. A method for recognizing a charging cable in an at least partly electrically driven vehicle, wherein the vehicle comprises an energy store that is able to be connected to an electrical energy source by way of a charging cable, the method comprising the acts of:
before each predetermined or predeterminable event:
detecting, by way of a control unit, whether the charging cable is situated in the vehicle;
if the charging cable is not situated in the vehicle, preventing starting of the engine by way of the control unit;
determining, by way of the control unit and based on a state of charge of the energy store, that a journey is able to be completed without using the charging cable; and
suppressing an output from being receive based on the determination, wherein
the output indicates the charging cable is not situated in the vehicle.
